Ecohydraulics-based environmental flow assessment in two arid North African rivers.

North Africa is among the most water-stressed regions in the world; still, the habitat requirements of its freshwater biota are largely unknown. In this study, (i) we developed habitat suitability curves (HSCs) for freshwater macroinvertebrates in two poorly studied, regulated North African rivers (Ziz and Oum Er-Rbia), and (ii) assessed environmental flows downstream of each river dam by incorporating the HSCs in two-dimensional ecohydraulic models. We demonstrate a low-cost sampling methodology combined with freely distributed ecohydraulic modeling software.

Vitamin K for Vascular Calcification in Kidney Patients: Still Alive and Kicking, but Still a Lot to Learn.

Patients with chronic kidney disease (CKD) suffer disproportionately from a high burden of cardiovascular disease, which, despite recent scientific advances, remains partly understood. Vascular calcification (VC) is the result of an ongoing process of misplaced calcium in the inner and medial layers of the arteries, which has emerged as a critical contributor to cardiovascular events in CKD. Beyond its established role in blood clotting and bone health, vitamin K appears crucial in regulating VC via vitamin K-dependent proteins (VKDPs).

Depressive Symptoms and Anger Expression Among Survivors After Stroke.

Introduction: Stroke is a frequent cause of death and one of the most common causes of disability and depression in the countries of the Western world. Depression is associated with limited functionality, reduced self-care, and increased mortality in patients with stroke. Anger often occurs in these patients and may disrupt the course of their recovery.

Investigation of Anxiety and Health Locus of Control in Patients Undergoing Hemodialysis.

Introduction: Hemodialysis is the most frequent treatment modality for End-Stage Renal Disease (ESRD). However, a number of limitations and modifications accompany this treatment, affecting people's physical and psychological well-being and increasing anxiety symptoms. The aim of this study was to investigate the level of anxiety and health locus of control among dialysis patients.

Modeling the Agia Zoni II tanker oil spill in Saronic Gulf, Greece.

We employed GNOME to simulate the oil spill due to the sinking of the tanker "Agia Zoni ΙΙ" in September 2017 in Saronic Gulf. We performed simulations using various combinations of wind and current input, and values of the GNOME parameters, and compared the simulated oil spill trajectories with coastal pollution and satellite data. The best scenario, i.
